are very tumid, the outline is much less regularly curved than in D. gloôosa, the umbones are 

 more prominent, and the concentric sculpture is coarser, less regular and much better marked 

 than in the latter species. The hinge teeth of D. globosa are more strongly developed and the 

 shell is thicker. 



Distribution: — D. bullata was described from Ceylon. 



In the "Siboga" collection the species is represented by shells collected in the Bay of 

 Bima (St. 47), St. 164 (i°42'.5S., i30°47'.5E., 32 mètres) and Banda Anchorage (St. 240).
